Download or read book The Relevance of Broker Networks for Information Diffusion in the Stock Market written by Marco Di Maggio and published by . This book was released on 2017 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper shows that the network of relationships between brokers and institutional investors shapes the information diffusion in the stock market. We exploit trade-level data to show that central brokers gather information by executing informed trades, which is then leaked to their best clients. We show that after large informed trades, a significantly higher volume of other institutional investors execute similar trades through the same broker, allowing them to capture higher returns in the first few days after the initial trade. In contrast, we find that when the informed asset manager is affiliated with the broker, such imitation does not occur. Similarly, we show that the clients of the broker employed by activist investors to execute their trades tend to buy the same stocks just before the filing of the 13D. This evidence also suggests that an important source of alpha for fund managers is the access to better connections rather than superior skill.
Book Synopsis Do Countries Matter for Information Diffusion in Financial Markets? Evidence from Global Supply-Chain Networks by : Ling Cen
Download or read book Do Countries Matter for Information Diffusion in Financial Markets? Evidence from Global Supply-Chain Networks written by Ling Cen and published by . This book was released on 2017 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document large cross-sectional variation in the speed of information diffusion between U.S. suppliers and their international principal customers. Based on the rigorous and comprehensive framework of risks in emerging markets from Karolyi (2015), we find that market operating efficiency is the predominant country-level characteristic among six major dimensions in explaining this cross-sectional variation. Our results are robust under both panel data analysis and a quasi-natural experiment using exogenous short-selling regulation changes. We suggest that country-level characteristics play an important and distinct role in determining the diffusion of firm-specific information in international financial markets. Our results indicate that stock price efficiency of U.S. firms is partially determined by the institutional and regulatory environment abroad.
Book Synopsis Essays on Information Diffusion and Stock Markets by : Aaron Paul Burt
Download or read book Essays on Information Diffusion and Stock Markets written by Aaron Paul Burt and published by . This book was released on 2017 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: My dissertation is a compilation of three separate research studies that explore how information diffuses in financial markets. The first chapter examines how non-uniform information diffusion through distinct networks segments U.S. financial markets. Using changes in newspaper ownership networks, I document that a network link between different geographic areas leads to increased comovement of turnover and returns between stocks headquartered in those areas. Consistent with delayed content sharing within a network, the largest increase in comovement is observed using weekly data. I show that the network-driven comovement is not driven by fundamentals and is weaker for large firms with high institutional ownership and decreases over time. I also document that a network link causes price levels of linked stocks to become more similar. My findings show that segmented information networks lead to segmented financial markets with implications for market efficiency, home bias, and the effects of changes in the U.S. media landscape on financial markets. The second chapter shows that investors do not fully monitor the information about directors available in the past prices of firms within the network the directors oversee. A long-short portfolio using this information yields an annual alpha of 6.6%. This predictability is limited to when firms share a director and is not driven by industry or previously identified economic links between firms. The predictability is largest in the long end, when small firms predict big firms, and when information on shared directors is costlier to obtain. Trading by the shared directors is a key mechanism: filtering on their trades increases the annual alpha to 15%. The third chapter studies the econometric properties of a commonly used network-based measure of information diffusion between economically linked firms. Previous studies use this measure to document failures of market efficiency with price discovery requiring up to a year. The measure is constructed as the long-short alpha of portfolios formed sorting on the preceding returns of firms economically linked to portfolio firms. We show that correlated alphas between linked firms bias these measures. Existing studies have monthly biases as large as a factor of two. This bias creates predictability even after price discovery completes. Subtracting the predicted return from the sorting firms' returns removes this bias. Eliminating this bias reveals a more efficient market than previously documented: price discovery takes one month.
Book Synopsis Information Diffusion Across Financial Markets by : Liang Ding
Download or read book Information Diffusion Across Financial Markets written by Liang Ding and published by . This book was released on 2010 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Financial markets demonstrate a large degree of comovement. Such comovement is important for a variety of investment and risk management decisions. This research is motivated by 2007-2008 financial turmoil. During the turmoil period, the markets co-move locally and globally, making it difficult for investors to hedge the risk. Although the cross market linkage is a topic of ongoing interest to researchers and practitioners, it seems that we are still in the preliminary stage to fully understand the cross market linkages, and even far away to prevent the crisis transmitting across markets. This dissertation attempts to answer two main questions, what are the major channels that link financial markets, and how those channels change in different periods. In this study, we examine two empirical tests on domestic markets and international markets linkage respectively. The first test focuses on the financial markets within U.S, and treats the stock, bond, CDS, stock option markets as a closely connected network. From 2004-2009, our tests find no evidence that static cross-market linkage becomes stronger in the crisis period than in the normal period. In terms of dynamic linkage, we find the information flow pattern become stronger in the crisis period. And we identify the role of volatility and liquidity in the financial network. The second test focuses on the international markets linkage using the derivatives market information. We use a family of volatility indexes from 1999-2009, including VIX, VSTOXX, VDAXNEW, VXJ, and VSMI, to filter the information diffusion through other channels. Therefore, the tests contribute a unique perspective to find out how the investors expect the interaction of the near-term volatility across U.S. and international markets. Our tests provide evidence that the linkages across corresponding markets are stable in the past decade. And we also find U.S. market plays a stronger role in a two way information flow structure with other markets through volatility linkage. The dissertation contributes a comprehensive research on the financial network linkage. The results obtained in this dissertation will improve our understanding of information diffusion process across financial markets and are expected to fill significant gaps in the current literature.
Book Synopsis Seeking Virtue in Finance by : JC de Swaan
Download or read book Seeking Virtue in Finance written by JC de Swaan and published by Cambridge University Press. This book was released on 2020-09-17 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Global Financial Crisis, a surge of interest in the use of finance as a tool to address social and economic problems suggests the potential for a generational shift in how the finance industry operates and is perceived. J. C. de Swaan seeks to channel the forces of well-intentioned finance professionals to improve finance from within and help restore its focus on serving society. Drawing from inspiring individuals in the field, de Swaan proposes a framework for pursuing a viable career in finance while benefiting society and upholding humanistic values. In doing so, he challenges traditional concepts of success in the industry. This will also engage readers outside of finance who are concerned about the industry's impact on society.

My findings show that segmented information networks lead to segmented financial markets with implications for market efficiency, home bias, and the effects of changes in the U.S. media landscape on financial markets.
Download or read book Investor Network written by Chung San-Lin and published by . This book was released on 2018 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we examine the information diffusion of firms in investor networks. Using a unique investor account-level dataset from the Taiwan Stock Exchange from 2005 to 2014, we identify the information diffusion of firms as their centralization in investor networks. Consistent with the theory of investor information networks, we find that central investors trade earlier and are more profitable than peripheral investors. Furthermore, they have greater access to superior, private information based on actual M&A events. More importantly, we find that centralized firms (i.e., firms with more central investors' networks) experience less delay in prices, and therefore demand lower price delay premiums than peripheral firms. These results suggest that investor networks speed up the incorporation of new information into asset prices, and cause the strength of information diffusion to have a great impact on stock returns.
Book Synopsis Information Networks by : Ankur Pareek
Download or read book Information Networks written by Ankur Pareek and published by . This book was released on 2012 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the effect of information networks on the trading behavior of mutual funds and on stock returns. An information or stock ownership linkage between two mutual funds is defined by large positions in the same stock. Mutual funds trade together with other funds in their information network after controlling for the overall trading behavior of the mutual fund sector. The effect is robust and cannot be explained by style investing or geographic location. The paper also examines the effect of the structure of information networks on stock returns and stock volatility. Using network density as a measure for the speed of information diffusion in a network of investors, I find that stocks with a lower network density demonstrate stronger return momentum over medium horizons and also show a delayed response to the market-wide information. The evidence is consistent with the gradual information diffusion model of Hong and Stein (1999). Finally, I provide empirical evidence in support of recent theoretical models that study the asset pricing implications of social networks. I show that centralized information networks lead to a higher volatility of individual stocks in the cross-section and also explain the variation in average stock idiosyncratic volatility over time.
Book Synopsis Essays on Information Transmission in Firm Networks and Financial Market Implications by : Christoph Maximilian Schiller
Download or read book Essays on Information Transmission in Firm Networks and Financial Market Implications written by Christoph Maximilian Schiller and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three chapters on firm-level production networks, information production and dissemination, and their impact on corporate policies and investment decisions. Chapter 1 provides an introduction of the essays and summarizes their main findings. Chapter 2 examines the role of international supply-chain relationships for the transmission of corporate Environmental and Social (E) policies, and the resulting impact on real E outcomes and firm performance. E policies propagate from customers to suppliers, especially when customers have higher bargaining power and suppliers are in countries with lower ESG standards. This transmission mechanism matters: suppliers subsequently reduce their toxic emissions, litigation and reputation risk decreases, and financial performance improves. Chapter 3 develops a measure for the speed of information diffusion along supply-chains and documents a causal relationship between the attention of key market participants, i.e. dual-covering analysts and cross-holding institutional investors, and the speed measure. The speed of information diffusion plays an important role for feedback effects from stock prices to corporate investments: supplier managers rely more on information in customer (supplier) stock prices when the speed of information diffusion along the supply chain is slower (faster). Consequently, the diffusion speed affects the coordination of relationship-specific investments between customers and suppliers and future operating performance of suppliers. Chapter 4 shows that international supply-chain links are an important channel for the propagation of financial contagion around the world. Following large country-level shocks, such as market-index jumps or natural disasters, dynamic conditional correlation (DCC) between U.S. suppliers and their foreign customers increases significantly, beyond country-level and industry effects. Consistent with a credit-chain mechanism, the effect is asymmetric for positive and negative shocks, more pronounced for supply-chain pairs with a closer relationship, higher leverage, lower cash holdings and firm profitability, and increases with the costs of bankruptcy resolution in the customers countries.

Book Synopsis Banking and Trading by : Mr.Arnoud W.A. Boot
Download or read book Banking and Trading written by Mr.Arnoud W.A. Boot and published by International Monetary Fund. This book was released on 2012-10-02 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the effects of a bank's engagement in trading. Traditional banking is relationship-based: not scalable, long-term oriented, with high implicit capital, and low risk (thanks to the law of large numbers). Trading is transactions-based: scalable, shortterm, capital constrained, and with the ability to generate risk from concentrated positions. When a bank engages in trading, it can use its ‘spare’ capital to profitablity expand the scale of trading. However, there are two inefficiencies. A bank may allocate too much capital to trading ex-post, compromising the incentives to build relationships ex-ante. And a bank may use trading for risk-shifting. Financial development augments the scalability of trading, which initially benefits conglomeration, but beyond some point inefficiencies dominate. The deepending of the financial markets in recent decades leads trading in banks to become increasingly risky, so that problems in managing and regulating trading in banks will persist for the foreseeable future. The analysis has implications for capital regulation, subsidiarization, and scope and scale restrictions in banking.

Available in PDF, EPUB and Kindle. Book excerpt: Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.

Download or read book Case Studies on Financial Markets written by Chiradeep Chatterjee and published by . This book was released on 2008-04-23 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: he days, when sovereign governments used to administer almost insulated economic systems, are gone. And gone with them is the age of savings by individual investors, secured and guaranteed by their respective governments. Post-globalisation, financial markets have become highly relevant to human society. Individual investors today look up to financial markets and have become savvy enough to tuck in the trends. From the macroeconomic viewpoint, interesting trends are the influence of the dollar on other nations, consolidation in financial markets, and the resurgence of Asian markets. The dollar s influence persists mainly due to the continued acceptance of the dollar as the anchor for international trade. This makes US domestic economic policy effects to spill over into the distant economies. On the one hand, globalisation abetted by proliferation of Internet has influenced this. To counter US supremacy, capital markets especially in Europe have resorted to integration. They have embraced modern technology in a big way, worrying the US capital markets. On the other hand, globalisation has helped Asian countries benefit from the proliferation of manufacturing technology; also making them economic powerhouses. Resurgent Southeast Asian economies were dubbed as Asian Tigers . These nations saddled by the vestiges of old practices smacked of red tape and nepotism. But economic imperatives have made them embrace professional management practices. Of late, India and China emerged as potential economic superpowers. Experts predict they will exert greater influence on financial markets. The book has been divided into three sections: US financial markets, European financial markets, and Asian financial markets. There are cases related to market innovations and how advantages from them have been nullified by human greed. Cases highlight issues relating to accounting principles and market regulations. Cases on European markets focus on how private equity has helped transform conservative businesses, integration of European bourses to counter US supremacy and other regulatory aspects. Finally, the Asian section focuses on the problems faced by Southeast Asian economies. Innovative instruments in Indian financial markets and inherent problems have also been discussed. This book will interest those people who want to get a deeper insight into the functioning of world financial markets.
